Is this new?"

  

The principle is not look particularly new.  Some amateurs in the UK 
have been trying to do something similar since the late 90's.  John Dews 
was a notable one and a couple of minutes of googling found this 
reference.  There are better explanations but the method is mentioned 
under item 5.

Here's a snip from the article:

"He monitors natural mite drop by checking the mites dropping through 
the Varroa screens, and he has coupled this with checking for damage 
such as legs bitten off. By selectively breeding from colonies that show 
high mite damage, using instrumental insemination, the queens were 
inseminated with semen from drones from colonies showing high mite damage"
